Abstract :
Modern construction industrial systems have a long history in different places, especially in Europe, and due to its advantages, it can be used in the construction industry and be effective in controlling energy consumption. Autoclaved aerated concrete (AAC) has been industrially produced as one of the building materials since the beginning of the 20th century.The lightweight porous structure and the speed of making most of the AAC blocks are among the advantages of this type of blocks, which, due to their structure, are a very effective moisture barrier as well as a significant thermal insulation against the conditions of the building's surrounding environment. Gilan province and the city of Rasht have a moderate and humid climate, and humidity control in this climate is one of the design requirements. In addition to this ease of implementation, the low density and generally suitable physical characteristics of AAC blocks can be investigated and compared with other conventional blocks in the construction of residential buildings in Rasht city; Therefore, in this research, which was done in a descriptive-analytical way, it is tried to answer the main question: can AAC blocks be introduced as an alternative to conventional materials in the construction of residential buildings in Rasht? The results show that in the comparison of the tested scenarios between simple clay blocks, simple cement blocks, foamed cement blocks and AAC blocks, by the software, simple cement blocks and insulated cement, if they are in accordance with the existing standards. Produced and used in accordance with the standards of relevant organizations, they can be effective in reducing energy consumption by up to 106% in gas consumption and up to 50% in electricity per year compared to conventional simple clay blocks in construction.
